FLASH_CR_SNB field has too many bits in stm32h503xx.h

[Jochen0x90h]

Hi!

I found a bug in stm32h503xx.h (version 2023)

The SNB field has too many bits:

#define FLASH_CR_SNB_Msk (0x7FUL << FLASH_CR_SNB_Pos)

Correct is only three according to the reference manual (8 pages of 8K flash), therefore it should be

#define FLASH_CR_SNB_Msk (0x07UL << FLASH_CR_SNB_Pos)

With kind regards,

Jochen

Hello @Jochen0x90h 

Let me thank you for posting and welcome to the ST Community.

Your request is under investigation, and I will get back to you ASAP.

For more investigation, I suggest please that you provide the MCU reference.

Thanks.

Hello Mahmoud,

which MCU reference do you need? The stm32h503xx.h header file is provided by ST for all STM32H503 devices. Was it possible to confirm and fix the bug?
